VEHICLE-WHEEL AND BEARING THEREFOR.

SPECIFICATION forming part of Letters Patent No. 734,918, dated July 28,1903.

Application filed November 20,1902. Serial No. 1 32,165 \No model.)

To all 2072,0722. it may concern:

Be it known that 1, WILLIAM L. MARTIN, a citizen of the United States,residing at Rancocas, in the county of Burlington, State of New Jersey,have invented a new and useful Improvement in Vehicle-Wheels and Bearings, of which the-following is a specification.

My invent-ion consists of an improvement in vehicle-wheels and bearingstherefor, the novel features of which being hereinafter set forth.

Figure 1 represents a longitudinal section of a wheel and bearingembodying my invention. Fig. 2 represents an elevation of a portion ofthe device, showing the balls. Fig. 3 represents an elevation of a plateemployed in detached position.

Similar letters of reference indicate corresponding parts in thefigures.

Referring to the drawings, A designates an axletree or bearing, which ishollow, as at B, and receives the spindle or journal U, the forwardportion (1 of which is squared or angular and is fitted in acorrespondingly-shaped opening in the hub E of the wheel, to which aresecured the spokes F, it being seen that said wheel rotates as one withsaid spindle and that the wheel is boxless.

In order to retain the wheel on the polygonal portion G I employ a nutG, which is fitted on the threaded stem H on the outer end of thepolygonal portion G Fitting within the opening B in the axletree A andaround the spindle G is a sleeve J, which is screwed or otherwisesecured to the block K, which is screwed or otherwise secured to theaxletree A, said block having a bearing or run for the balls L, theother bearing or run for said balls being in the plate or disk M, whichis rigidly secured to the hub E of the wheel in the present instance byengagement with the ring U, which is rigidly secured to the hub E, saidring U entering recesses V in the plate M, it being seen that the endportion of the axle, the balls and bearing therefor are in a recess inthe hub E, provided therefor.

N designates a block secured to the sleeve J and in which is a bearingor run for the I balls P, the other bearing being in the nut Q, which isscrewed or otherwise secured to the inner end of the spindle 0.

Any suitable means may be employed for lubricating the parts. Forexample, suitable ducts may be made in the axletree, it being seen thata suitable space or passage is formed between the spindle O and thesleeve J and that aspace or passage-S is formed between the hub E andthe axletree A, while a space or passage T is formed between the nut Qand the axletree A, the effect of all of which is evident. In thismanner thespindle O rotates with reduced friction, and consequently moreeasily, and the bearings thereof are the balls L and P; The forwardportion of the axletree being within the hub, the weight is over theadjacent portion of the axletree, and.

the far end of the spindle will not tilt when the vehicle is on a level.

It will be noticed that the ring U, which is between the plate M and thehub E, takes part of the weight from the polygonal portion of the hub.

W designates a ring which is' adapted to prevent the plate M fromrotating on the spindle after said plate is in proper position thereon,said ring W being provided with a lug or tongue A, which is adapted toenter a recess B in the polygonal portion of the spindle, whereby thering cannot rotate with respect to said spindle.

D is a plate or washeron the threaded stem H and against which the nut Gbears, as seen in Fig. 1;

Gdesignates a pin on the ring W, which is adapted to enter one of theopenings D, formed in the plate M, whereby the plate is locked withrespect to the said spindle.

It will .be evident that various changes may be made in the details ofconstruction which will come within the scope of my invention, and'I donot, therefore, desire to be limited in each instance to the exactconstruction herein shown anddescribed.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. A wheel-hub having a chamber, a chambered axletree having its outerend located within the chamber of the hub, a spindle, a ball-bearing forthe inner end of the spindle within the chamber of the axletree, aballbearing within the chamber of the hub, means securing the outer endof the spindle to the hub to rotate therewith, and means located \vithinthe chamber of the hub for engaging the adjacent ball-bearing to lock itwith respect to the spindle.

2. A chambered wheel-hub, a chambered axletree, a spindle, aball-bearing for the inner end thereof within the chamber of theaxletree, a ball-bearing within the chamber of the hub and a ringlocated within a recess within the chamber of the hub and engaging theadjacent ball-bearing and having means connecting it with the spindle.

3. A chambered wheel-hub, a ring rigidly secured within the same, aplate having recesses engaged by portions on said ring, a spindlehavinga polygonal portion engaginga corresponding opening in said plate,means securing the outer end of the spindle to the hub, a ball-bearingfor the inner end of the spindle, a chambered axletree, a block securedwithin the same and a sleeve secured to said block and to the bearing ofthe inner end of the spindle.

4. A chambered wheel-hub, a plate within said chamber and movable withthe hub and having openings, a ring seated in a recess in the chamberedhub and having a pin engaging one of said openings in the plate, a ringsurrounding said plate and interposed between the same and the innerwall of the chamber of said hub, a spindle, a hollow axletreesurrounding the same, a sleeve within the axletree, a block secured tosaid sleeve for cooperation with said plate to form a raceway for balls,ball-bearings at the inner end of the chamber of the axletree, and meanson the outer end of the spindle bearing against the outer face of thehub.

5. Achambered hub, a plate therein, a ring around said plate, a ringseated within the recess in the chamber of the hub and having means forengagement with said plate, a spindle having. threaded portion uponwhich said plate is screwed and having a polygonal portion fitting acorrespondingly-shaped opening in said last-mentioned ring and in theouter face of the hub. said spindle being formed with a recess in itspolygonal portion to receive a tongue on the adjacent portion of thering, ball-bearings for the inner and outer ends of the said spindle,the said plate having peripheral recesses receiving portions of the ringsurrounding the plate, and means for securing the outer end of thespindle in position.
